SAMUEL SOLLIDAY, OF SUMNEYTOVN, PENNSYLVANIA.

SAFETY-CASING FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 27,317, dated February 28, 1860.

To all whom it may concern:

Be it known that I, SAMUEL SOLLIDAY, of Sunineytown, in the county of Montgomery and State ot Pennsylvania, have invented a new and useful Improvement in the Construction of Vessels for Preventing Injury from Explosion of Steam-Boilers therein; and I do hereby declare that the following is aI full, clear, and exact description of the same, reference being had to the annexed drawings, forming part of this speciiication, in the several figures of which similar characters of reference denote the same part.

Figure l is a side elevation of the boilercasing. Fig. 2 is a View of top of the casing. Fig. is a view showing the bottom thereof. Fig. 4 is a vertical section of portion of the casing through the door. Fig. 5 is a horizontal section ot same.

The object of this invention isthe prevention of injury to vessels from the explosion of a steam-boiler thereon.

The invention consists in the construction of a easing orwell for the reception ot the boiler, of a strong frame-work of timber having a lining of stout boiler-iron, said casing extending above and below deck and having a covering ot lighter construction than the other parts of the construction, which in event ot explosion will be blown off, and the results of the explosion thus be left free to be discharged into the water. This construction will be readily understood by reference to the drawings, in which the several parts are thus represented.

g c a a represent a system of radial timbers with ties I), built iirmly together to form the bed of the casing.

c c c are nprights, and tl (l braces firmly framed into the bed-pieces. Upon the uprights are cap-pieces e c, the whole lined with stout boiler-plate iron, as shown at f. This constitutes a casing orwell tor the reception of the boiler, made of such strength as to resist the destroying tendency of an explosion.

Upon the casing is the cover C, of lighter construction than the body of the casing and provided with shutters s for light or ventilation. This casing has an opening, o, provided with a strong door opening inward in the portion above the deck of the vessel, serving as a man-hole to admit of access to the boiler.

The construction herein described and figured in the drawings may be varied in many ways so long as the object in view is not lost sight of-this being the incasing of the boiler in an apart-ment suiiiciently strong to prevent explosion from injuring the hull of the ship. In event of an explosion of a boiler thus protected the results will either be retained in the chamber, or, carrying ott the top C, will ily overboard, and thus et'fect no injury to the ship.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The incasingot' marine steam-boilers within a chamber of sutiicient strength to withstand the effect of explosion in all parts except its top, as set forth.

In testimony whereof I have hereunto signed my name before two subscribing' witnesses.

SAML. SOLLIDAY.
